One big reason I want to be efficient with work tasks is to have time for play. I’m a computer gamer. Unfortunately, this means Windows directly on the hardware (as opposed to emulation or virtualization from a different host OS.) This also means, I should be prepared to regularly rebuild it.
It only supports Windows XP+, but I don’t see this as a serious drawback as Knoppix can be used to recover from Linux problems I’ll encounter (generally my own stupid mistakes). Driveimage XML fits the bill for an easy way to get back to a clean Windows XP without going through the install, pre-SP2 patch, SP2 patch, and finally post-SP2 patch.
